Keeps nagging me about backups to Google! If I would want my data with Google, I'd just use the Google Authenticator..... No other backup option... Also, I haven't found how to remove an obsolete account. Uninstalled! Added: Yes, I can export and import, but that will not stop the app from nagging me about backups to Google. Update2: I think I've checked it all, and didn't find it. I've definitely must have looked everywhere it logically could be.

Go to Settings, the third section from the top is Appearance (under 2FAS Backup and Security), and inside you'll find the toggle "Google Drive sync reminder" as the second one from the bottom, above "Hide Tokens".

The app is almost perfect and simple, but there are two issues imo. One, the fingerprint scan doesn't start when the prompt is displayed and it takes the app some time to interact with the sensor, and even after a successful scan, it takes its time to display an animation which is rather long. Two, the amount of icons available for accounts is too low. Support for 3rd party icon packs would be nice

Hi Armin! Thank you so much for your review and suggestions! We'll take them into consideration for future improvements! As for the icons right now we offer more than 200 of them. Do you have some specific ones in mind that are missing?

I guess I can only edit my response and not reply back to you. I apologize because I might have overreacted when I lost my stuff in the Microsoft authenticator app. I remembered I had a pass key to this app. I resolved the display issue—so thank you for your help! I do have another question, though. As I’ve been switching my accounts to this app, I noticed I have a duplicate entry. If I delete one of them, will the other remain unaffected? Thanks in advance!

Make sure that both of them have the same secret key and generate the same code every 30 seconds. If they do, feel free to move one of them to trash. Just in case you'll be able to restore it from there 😉
